State the slope and $y$y-value of the $y$y-intercept of the equation, $y=2x+3$y=2x+3

Consider the equation $y=-1-\frac{9x}{2}$y=−1−9x2.

Write down the equation of a line whose slope is $-8$−8 and crosses the $y$y-axis at $-9$−9. Express in slope-intercept form.

Write down the equation of the line in slope-intercept form, given that its slope is $-3$−3 and its $y$y intercept is $-2$−2.

Determine the equation of a line from information about the line
